The co-efficient of q in sum of the given expression is 2

Step-by-step explanation:

Given expressions are $\frac {2}{3q}-\frac {3}{4}$ and $\frac{-1}{6q}-r$

Now sum the given expression

$\frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q} -r = \frac{4-1}{6q} -\frac{3}{4} -r$

$\frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q} -r = \frac{3}{6q} -\frac{3}{4} -r$

$\frac {2}{3q}-\frac {3}{4} + \frac{-1}{6q}-r =\frac{1}{2q} - \frac{3}{4} -r$

Here the co-efficient q is 2 (since $\frac{1}{q} = \frac{1}{2}$ )
